Concept
Data Quality
The metadata quality score out of 100 of a catalogue record, the required and recommended fields, and the TR Dizin data checks for articles.
Every catalogue record has a metadata quality score out of 100. The score shows how complete the record is. A record with a missing required field cannot be published. Recommended fields do not block publishing, but they help the record to be found, indexed and cited correctly.
Score calculation
Required fields make up 60 points of the score and recommended fields 40. Each missing required field lowers the score by 12. The points for recommended fields depend on the share of fields that are filled in. When you correct and save the record, the score is calculated again.
Required fields
The required fields depend on the record's type. The list for each type is in Catalogue Rules. The record's Metadata quality card lists the missing required fields under the Required heading. When nothing is missing, the card says Ready to publish.
Recommended fields
For every type, an English title, an abstract, an English abstract, keywords, a licence and a persistent identifier are recommended. For all types except journals, the rights holder, the publication year, ORCID iDs for all authors, the authors' institutions and a full-text file are recommended too. A record whose access is metadata only is not expected to have a full text.
| Type | Extra recommended fields | Expected persistent identifier |
|---|---|---|
| Book | Publisher, category, cover image | ISBN-13 |
| Children's book | Publisher, category, cover image | ISBN-13 |
| Journal | Publisher, category, cover image | ISSN or e-ISSN |
| Proceedings paper | Publisher, category | DOI or ISBN-13 |
| Thesis | Publisher, category | Handle, DOI or another identifier |
| Book chapter | No extra field | DOI or ISBN-13 |
| Article | No extra field | DOI |
TR Dizin data checks
For articles, the card also shows the TR Dizin data checks warnings. TR Dizin is Türkiye's national citation index. These warnings check details such as the English abstract, the authors' ORCID iDs and institutions, the received and accepted dates, the references, the ethics committee statement and the DOI. The warnings do not block publishing the record. If the journal makes the TR Dizin check mandatory, they block publishing the issue. The details are in Preparing for TR Dizin.
Finding the gaps
The Data Quality Screen lists the gaps in the whole catalogue by score. The Missing data filter in the Publications list also finds records with no licence, no category, no abstract or no English translation.
